Taking a New Shot At a TB Vaccine
Summary
For many people around the globe, there's only one line of defense against Mycobacterium tuberculosis: a shot of a 90-year-old problematic vaccine that they get shortly after birth. The emergence and rapid spread of multidrug-resistant strains of M. tuberculosis and the United Nations's goal of halving TB deaths by 2015 have led to an influx of private and public money to develop a new vaccine. Now the most advanced of these candidates are entering their first human efficacy trials. But with this new hope come challenges. Researchers are wrestling with how to select the best candidates to advance to much larger trials—and they are wondering how to pay for those final rounds of testing. Nor are there any guarantees of success at the end of this road. A human trial of one new tuberculosis vaccine was halted at the end of September because of apparent side effects.

Yes, but "money" is not necessary. We simply say "to pay for" something. In today's society, we usually pay with money so unless you are paying with something else, it's not necessary to specify.
I'd go further and say that putting money in the sentence would be very unnatural.
Thank you.
I can think of an occasion when we would use "money" with "pay" but not on its own.
A man has just spilt a cup of coffee all over a woman's white coat. She is understandably upset and says "OY! IDIOT! I paid good money for that coat!"
When we say we "paid good money" for something, it means it was relatively expensive.
And. on the other hand, 'paying for something' doesn't have to mean paying money. If someone says 'You'll pay for this' it usually means - 'You'll suffer appropriately, or make amends in some way.'
